“…Millimeter wave (mmWave) wireless communication systems are expected to play a significant role in the improvement of per user data rates in the next few years, due to the wide available bandwidths [1]. The combination of millimeter wave frequencies with MIMO techniques makes it possible to achieve data rates of several Gbit/s, especially if the transmission is line of sight (LOS) dominant [2].…”

Measurement results for millimeter wave LOS MIMO systems are presented with a focus on time variation and multipath propagation. Different system setups are used, including 2×2 and 3×3 MIMO, and involving different synchronization procedures and front-ends. Furthermore, different propagation scenarios are evaluated, covering a wide area of applications. The results show that the LOS component carries significantly more power than the NLOS components, and that frequency selectivity from front-ends should be taken into account when designing these high bandwidth systems. Frequency offsets and other phase variations due to transmit and receive oscillator differences are treated as part of the channel and thus, depending on the synchronization setup, the MIMO system exhibits different time variations, particularly in the case of independent local oscillators. It is also observed that these systems experience significant non-trivial long-term variations in terms of amplitude and phase.

“…For that reason, although there is already some literature on mmW measurements in tunnels at 30 GHz [9], 38 GHz [10], 60 GHz [11], and 240 GHz [12] bands, there are no measurements in a realistic railway environment.…”

The next generation of mobile communications, 5G, will provide a wideband network based on microwave and millimeter-wave (mmW) communication radio links with the goal of fulfilling the strict and severe requirements of the future test cases. In particular, this paper research is focused on mmW bands in metropolitan railway tunnels. For that purpose, a propagation measurement campaign was performed at 24 GHz band in a passenger train on a realist subway environment, and these results were combined with simulations ad hoc for tunnels and a theoretical modal propagation model. A narrowband and a wideband study have been conducted with the aim of obtaining the path loss, fading, power-delay profile, and angle of arrival, taking into consideration horizontal and vertical polarization in the receiving and transmitting antennas. This validation can be used to design and deploy wideband mobile communication networks at mmW bands in railway scenarios.

“…Additionally, the environment conditions that dramatically decrease the reliability of FSO systems have trivial effects on mmWave transmissions. However, mmWave bands are heavily affected by rainy conditions and oxygen absorbance, and considered as more susceptible to security assaults [6], where FSO links have very high strength. The complementary behaviors of both transmission technology against different conditions pave the way for parallel employment of mmWave and FSO links to satisfy quality of service requirements of 5G and beyond networks [7].…”

Bearing in mind the high data rate and volume requirements of 5G and beyond networks, millimeter wave (mmWave) systems can be utilized with the assistance of free-space optical (FSO) systems since both technologies exhibit distinctive behaviors under different weather conditions. Therefore, in this study, we investigate a relay-based dual-hop hybrid FSO-mmWave systems from an outage performance point of view, where the communication in each hop is established on both FSO and mmWave links simultaneously. Specifically, Nakagami-m distribution is used for mmWave fading channels, while gammagamma distribution is assumed for FSO turbulence channels. Two well-known amplify-and-forward (AF) relaying schemes are examined during data transmission, in which the power amplification operation is based on partial and full channel state information of the system, namely, fixed-gain and variable-gain AF relaying methods. The effects of fundamental system variables on the outage analysis of the relay-based hybrid transmissions are investigated by obtaining exact closed-form derivations of the outage probability and effective throughput. Based upon the results, it is shown that the proposed closed-form expressions are in good match with the Monte-Carlo simulations.
